How to reset canon ip4600

what do you mean by reset? you mean resetting the device to it's factory settings or resetting it to recognize the refilled cartridge? if it's second one it can be a problem, because as far as i know the new line models (such as 4600) has different chip inside the ink cartridge and because of that fact there's still no resetter for the new models. you can try holding the resume button for a few seconds after inserting the cartridge but i doubt it will do the work. i will ask my friend 2moro and will report back
